The 2010 Ford expedition was parked in a driveway not on an incline. While in park it rolled backwards across a street and crashed into a tree. After the incident it was determined that with the engine turned off and the key removed the car could be put into any gear. It was further determined that the key could be removed with the engine off and the car in drive or any other gear. *tr

What stands out
No new NHTSA powertrain complaint has been filed on this vehicle in over 14 years — the issue may be aging out of the active population.
The failure pattern owners describe
Buyer takeaway: The 2010 Expedition's transmission has widespread issues ranging from violent slippage and hard catches to unintended park disengagement and inability to accelerate for passing—dealers often fail to replicate problems or offer permanent fixes. Multiple owners report dangerous situations and repeated repair attempts that don't resolve the core failures, making this model particularly risky for used-car buyers.
Owners report six distinct transmission failure patterns in the 2010 Expedition. Most severe is transmission slippage during overdrive downshifts after extended highway driving, followed by violent catches that jolt the entire vehicle and damage U-joints. A second critical issue involves loss of power when attempting to pass—the engine revs but vehicle won't accelerate, creating traffic hazards. Several owners document the transmission shifting out of park without driver input, allowing the vehicle to roll backward or forward into stationary objects; one owner reports the key could be removed with the vehicle in any gear, not just park.
Owners also report rough, jerky shifts with clunking sensations during normal acceleration and deceleration, transmission slipping and jumping gears from stops, and noisy operation with the vehicle creeping about 12 inches while parked. Dealership responses are inconsistent: some perform repeated transmission software updates that provide only temporary relief, others claim the behavior is "vehicle design," and many cannot reproduce the failures despite extended testing. One owner brought the vehicle to the dealership nine times in eight months for transmission work. No owner reports permanent resolution of their transmission issues.

Failure modes owners describe
Transmission slip and catch on downshift from overdrive
Severe transmission slippage occurs when downshifting from overdrive, typically after extended driving (2+ hours). Slippage is followed by hard catches that jolt the vehicle violently. Owners report the transmission slips and catches repeatedly, particularly when cruise control tries to maintain speed on inclines, damaging U-joints and drivetrain components.
When: After 2+ hours of driving; occurs on highway inclines with cruise control engaged
Symptoms owners cite: Transmission slips when downshifting from overdrive; Hard catch after slippage jolts the vehicle; Violent shuddering when transmission engages; Cruise control malfunction on inclines
Repairs/costs cited: Dealers unable to reproduce; inspection equipment revealed no problem after 5-minute test drive. U-joints and other drivetrain components damaged by repeated slip/catch cycles.
Recalls/TSBs owners mention: Ford investigated complaint but determined no problem found. Dealer initially attributed to vehicle break-in.
Loss of passing power / transmission shift hesitation
When attempting to accelerate for passing, the transmission attempts to shift into passing gear, engine RPM increases, but vehicle does not accelerate. After a few seconds, a mild bang and shudder occurs when driver releases throttle. Vehicle unable to gain speed needed to pass, creating hazardous traffic situations.
When: Random occurrences; has happened at least 3 times documented
Symptoms owners cite: Engine revs but vehicle will not accelerate; Delayed power delivery during passing attempts; Mild bang and shudder when releasing pedal; Low-speed transmission operation erratic; Unable to build speed for safe passing maneuver
Repairs/costs cited: Transmission software updates performed twice; issue recurs after 3-4 months. Updates provide temporary relief for low-speed erratic operation but not sustained.
Recalls/TSBs owners mention: Dealership advised transmission software updates needed; updates performed twice with recurring issues after short intervals.
Vehicle shifts out of park and rolls unintentionally
Vehicle shifts out of park without driver input while idling with park engaged or after being parked. Vehicle rolls backward or forward and crashes into stationary objects (post, tree, building). In one case, key fell out of ignition during rollback. In another case, vehicle could be shifted into any gear or have key removed with engine off and transmission in any gear (not just park).
When: While parked in park; incidents documented at 47,000 miles and 247,000 miles; early in ownership at 2,100 miles
Symptoms owners cite: Vehicle shifts out of park spontaneously; Vehicle rolls backward across parking area; Vehicle rolls forward with engine off; Key can be removed with vehicle in gear; Vehicle can be shifted into any gear with engine off; Brake light pedal disengages or shift interlock fails
Repairs/costs cited: Independent mechanic found vehicle non-drivable. Dealership stated malfunction was vehicle design; no repair performed. No diagnostic work documented.
Recalls/TSBs owners mention: Dealership claimed the park/shift behavior was vehicle design as intended; no repair offered or performed.
Rough shifting with clunk or kick sensation
Transmission produces rough, jerky shifts with clunk or kick feeling when accelerating or decelerating. Shifting becomes inconsistent and unpredictable. No warning lights precede failures. Issues confirmed by multiple independent transmission mechanics.
When: Random occurrences during normal driving; no specific mileage pattern documented
Symptoms owners cite: Rough shifting with clunk sensation; Kick feeling when changing gears; Rough shifts during acceleration; Rough shifts during deceleration; No dashboard warning lights; Random onset without prior warning
Repairs/costs cited: Inspected by 3 independent transmission mechanic shops; all confirmed the malfunction. No repairs documented in narrative.
Transmission gear slipping and jumping under load
Transmission slips and jumps gears during acceleration from stops or low-speed maneuvers. Engine RPM spikes without corresponding power delivery. Vehicle brought to dealership 9 times in 8 months for transmission issues. Owner reports fear of driving vehicle due to repeated unresolved failures.
When: At low speeds during acceleration from stops; early ownership at 9,000 miles
Symptoms owners cite: Transmission jumps gears during acceleration; Transmission slips under load; Engine revs without power delivery; Hazardous traffic situations created by power loss; Repeated failures despite multiple repair attempts
Repairs/costs cited: Transmission serviced multiple times across 9 dealership visits in 8 months; recurring slipping and jumping not resolved.
Transmission noisy operation and creep when parked
Transmission produces loud noise when driving and accelerating. Vehicle creeps approximately 12 inches while parked, suggesting brake hold issue or transmission creep. AC system also malfunctioning. Owner reports 10+ service visits for these combined issues.
When: Chronic issue during ownership; 10+ service visits documented
Symptoms owners cite: Very loud noise when driving; Noise when accelerating; Vehicle creeps about 12 inches while parked; AC system malfunction
Repairs/costs cited: Owner has taken vehicle to mechanic at least 10 times for transmission and AC complaints; issues persist.

Transmisin problem bery noise when driving and press gas. Sometimes when is parked it moves like 12" . Ac always a problem toke to mecanic at lease 10 times I'm so tired if this.
Transmission severely slips when downshifting from overdrive...only happens after driving for 2 or more hours. Have had it in 3 times, but dealer only would document it once. The first 2 times, they said the car was still breaking in and that it would settle in after a few more thousand miles. The 3rd time the dealer hooked up equipment and drove it for 5 min, returned and said no problem…
